Question

Perfusion is MOST accurately defined as the:

A) ability of the systemic arteries to constrict as needed to maintain an adequate blood pressure.
B) effective removal of carbon dioxide and other metabolic waste products from the body's cells.
C) circulation of blood within an organ in adequate amounts to meet the body's metabolic needs.
D) effective transfer of oxygen from the venules across the systemic capillary membrane walls.

Answer 1

Perfusion is the circulation of blood within an organ in sufficient amounts to meet the body's metabolic demands, involving oxygen and nutrient delivery and waste removal. So, the correct answer is option c

Step-by-step explanation:

Perfusion is most accurately defined as the circulation of blood within an organ in adequate amounts to meet the body's metabolic needs. It encompasses not just the flow of blood, but also the delivery of oxygen and nutrients to the tissues while removing carbon dioxide and other metabolic waste products.

This process is dependent on blood flow, which is the movement of blood through a vessel, tissue, or organ, typically driven by the contraction of the heart's ventricles. The cardiovascular system regulates the distribution of blood, ensuring that adequate blood flow is allocated to different tissues based on their current metabolic requirements. This is necessary for maintaining the overall function of organs and the entire organism.

So, the correct answer is option c,
